My spousal-unit helped me shoot a little test with the recently acquired Sony FS7 and DJI Ronin - the camera is at the limit of camera length for the gimbal, and any heavier lenses would probably push the camera even further back, most likely causing the camera to hit the back of the roll arm.
The first clip had a little bit of Warp Stabilizer (I was running holding the Ronin from the top handle), every other clip has had zero post-stabilization.
This was shot entirely on a Canon 17-40 f4 L series with Metabones Speedbooster adapter. Shot in S-Log 3, 1920x1080 120fps @ 50Mb/s, quick grade with Impulz LUTs and Fast Colour Corrector. Really happy with the performance of both the Ronin and FS7!
